Abstract
The utility model provides a damper oil sealing device, comprising an oil seal, an oil sealing seat and an oil sealing guider. The oil sealing seat further comprises a connecting rod insertion part which is a hollow circle sheet and a first support part which is a hollow circle cylindrical shell. One end of the first support part is fixedly connected to the outer edge of the connecting rod insertion part. A second support part is a hollow circle sheet. One end of the second support part is fixedly connected to the other end of the first support part. A sealing part is a hollow circle cylindrical shell. One end of the sealing part is fixedly connected to the other end of the second support part. Compared with the prior art, the damper oil sealing device is advantageous in that a seam welding mode is adopted to seal the oil sealing seat and an oil storage cylinder, and thereby sealing performance is bettered, oil leakage is prevented and service lifetime is prolonged.
Description
Technical field
The utility model relates to a kind of assembly of automobile with vibration damper, is specifically related to the improvement oil-sealing arrangement that a kind of vibration damper is used.
Background technique
Vibration damper is concussion when being used for suppressing bounce-back after the spring shock-absorbing and the energy that absorbs road shocks.When driving the vehicle that vibration damper broken down, can know from experience automobile through the spring that each cheats the hole, the back repercussions that rise and fall ripple, and vibration damper is used for suppressing this spring just.Do not have the bounce-back of vibration damper, will produce serious spring when automobile runs into rugged road surface, cross the forfeiture that yet can cause tire earth-grasping force and tracking property when bending because of the concussion about the spring with uncontrollable spring.
The oils liquid that damping is used is equipped with in vibration damper inside, in order to prevent leakage of oil, in vibration damper, oil sealing will be installed, oil sealing between piston rod and oil storage cylinder, vibration damper through the oil sealing passing shaft to defeating tight guider and clutch release slave cylinder.
A kind of oil sealing mounting type of existing technology is as shown in Figure 1; Oil sealing base 10 is a flat structure; Directly be socketed on the connecting rod 20; During sealing oil storage cylinder 30 flange are engaged with the plat part 11 of oil sealing base 10, the oil sealing base 10 of this structure is bad with oil storage cylinder 30 closed performances, is prone to produce the problem of leakage of oil.
The model utility content
To above-mentioned defective, the utility model provides a kind of shock absorber fluid seal apparatus of seam weldering mode with oil sealing base and oil storage cylinder sealing that adopted, to solve the bad technical problem of existing technology flange engaged closed performance.
For realizing above-mentioned purpose, the technical characteristics below the utility model has adopted:
A kind of shock absorber fluid seal apparatus comprises oil sealing, oil sealing base and oil sealing guider, and said oil sealing base further comprises a connecting rod insertion part, and said connecting rod insertion part is a hollow circular lamellar body; One first support part, said first support part are a hollow circular cylindrical shell, and an end of said first support part is fixedly connected with the outer of said connecting rod insertion part; One second support part, said second support part are a hollow circular lamellar body, and an end of said second support part is fixedly connected with the other end of said first support part; One sealed department, said sealed department are a hollow circular cylindrical shell, and an end of said sealed department is fixedly connected with the other end of said second support part, during assembling the outer rim of said sealed department and the inner edge seam weldering of oil storage cylinder are got up, and reach to prevent that fluid from spilling the function of coming.
According to the described shock absorber fluid seal apparatus of the utility model preferred embodiment, the said connecting rod insertion part and first support part and second support part and sealed department is one-body molded processes.
Owing to adopted above technical characteristics, make the shock absorber fluid seal apparatus of the utility model compare the shock absorber fluid seal apparatus of existing technology, the airtight performance of oil sealing base and oil storage cylinder is better, can prevent that more the problem of leakage of oil from occurring.
Description of drawings
Fig. 1 is the scheme of installation of a kind of shock absorber fluid seal apparatus of existing technology;
Fig. 2 is the cross-sectional view of the oil sealing base of the utility model;
Fig. 3 is the scheme of installation of the utility model shock absorber fluid seal apparatus.
Embodiment
Below in conjunction with accompanying drawing, the utility model done being described in further detail.
Please refer to Fig. 2, and Fig. 3, Fig. 2 is the cross-sectional view of the oil sealing base of the utility model, Fig. 3 is the scheme of installation of the utility model shock absorber fluid seal apparatus.The utility model oil-sealing arrangement is mainly used on the automobile absorber; Comprise oil sealing 45, oil sealing base 40 and oil sealing guider 46; Said oil sealing base 40 further comprises a connecting rod insertion part 41; Said connecting rod insertion part 41 is a hollow circular lamellar body, during assembling piston rod 50 is inserted in the oil-sealing arrangement by connecting rod insertion part 41; One first support part 42; Said first support part 42 is a hollow circular cylindrical shell; One end of said first support part 42 is fixedly connected with the outer of said connecting rod insertion part 41, and its main function is combining said connecting rod insertion part 41 that oil sealing 45 is coated on the inside closely, prevents that fluid from spilling; One second support part 43, said second support part 43 is a hollow circular lamellar body, and an end of said second support part 43 is fixedly connected with the other end of said first support part 42, and its main function is in the support as said oil sealing guider 46; One sealed department 44; Said sealed department 44 is a hollow circular cylindrical shell; One end of said sealed department 44 is fixedly connected with the other end of said second support part 43, during assembling the outer rim of said sealed department 44 and the inner edge seam weldering of oil storage cylinder 60 is got up, and reaches to prevent that fluid from spilling the function of coming.
The said connecting rod insertion part 41 and first support part 42 and second support part 43 are made of one piece with sealed department 44.
In sum, owing to adopted above technical characteristics, make the shock absorber fluid seal apparatus of the utility model compare the shock absorber fluid seal apparatus of existing technology, the airtight performance of oil sealing base and oil storage cylinder is better, can prevent that more the problem of leakage of oil from occurring.
More than disclosed only be the preferred embodiment of the utility model, but be not to be used for limiting itself, anyly have the knack of those skilled in the art, can think of without prejudice to following of the situation of the utility model variation, all should drop in the protection domain of the utility model.
